TECHNICAL FIELD

The present disclosure relates to a folding mat and, more particularly,to a folding mat for preventing noise between floors.

BACKGROUND

As people's contactless lives are routinized since the advent ofCOVID-19, residential spaces are evolving into multi-layered spaces thatproject lifestyles and personal lives. Under these circumstances,people's indoor living and activities are increasing compared to asituation before the advent of COVID-19.

An increase in indoor living and activities may inevitably beaccompanied by concerns about the generation of noise between floors dueto impacts applied to a floor surface of a living space such as a livingroom. Furthermore, a situation in which the floor of the living spacebecomes dirty or is scratched by foreign substances may increase.

In order to solve this inconvenience, people have installed the floormat on the floor surface of the living space. However, inconveniencesthat may not be solved remain in the conventional floor mat.

For instance, in a situation where a child's activity area is notrestricted, a mat that is large enough to cover the entire living roommay be required. However, it may be impossible to install and deliverthe mat of this size due to the characteristics of a general housingtype. The reason is because the internal height of an elevator in atypical apartment is about 2.5 m but the size of the mat to cover theentire living room is much larger than this.

For this reason, a large-sized mat is limited in delivery service, and aprofessional construction team should construct the mat, resulting inhigh installation costs.

DETAILED DESCRIPTION

Various embodiments and/or aspects are now described with reference tothe accompanying drawings. In the following description, for the purposeof explanation, numerous specific details are set forth in order toprovide a thorough understanding of one or more aspects. However, itwill be apparent to those skilled in the art that such aspect(s) may bepracticed without these specific details. The following description andaccompanying drawings set forth in detail certain illustrative aspectsof one or more aspects. However, these aspects are illustrative, some ofvarious methods in principles of various aspects may be employed, andthe descriptions are intended to include all such aspects and theirequivalents. Specifically, as used herein, “embodiment”, “example”,“aspect”, “illustration”, etc. may not be construed as advantageous overany aspect or design described herein.

Hereinafter, the same or similar elements are denoted by the samereference numerals, and overlapping descriptions thereof are omitted.When it is determined that the detailed description of the known artrelated to the present disclosure may obscure the gist of the presentdisclosure, the detailed description will be omitted. In addition, theaccompanying drawings are only for easy understanding of embodimentsdisclosed in the present specification, and the technical ideasdisclosed in the present specification are not limited by theaccompanying drawings.

It will be understood that, although the terms “first”, “second”, etc.may be used herein to describe various elements, these elements shouldnot be limited by these terms. These terms are only used to distinguishone element from another element. Thus, a first element discussed belowcould be termed a second element without departing from the technicalideas of the present disclosure.

Unless otherwise defined, all terms including technical and scientificterms used herein have the same meaning as commonly understood by one ofordinary skill in the art to which the present disclosure belongs. Itwill be further understood that terms used herein should be interpretedas having a meaning that is consistent with their meaning in the contextof this specification and the relevant art and will not be interpretedin an idealized or overly formal sense unless expressly so definedherein.

In addition, the term “or” is intended to mean an inclusive “or” ratherthan an exclusive “or.” That is, unless otherwise specified or clearfrom the context, “X employs A or B” is intended to mean one of naturalimplicit substitutions. In other words, when X employs A; X employs B;or X employs both A and B, “X employs A or B” may be applied to any ofthese cases. It should also be understood that the term “and/or” as usedherein refers to and covers all possible combinations of one or more ofthe listed related items.

It will be further understood that the terms “comprise”, “include”,“have”, etc. when used in this specification, specify the presence ofstated features and/or elements, but do not preclude the presence oraddition of one or more other features, elements, and/or groups thereof.Further, in the present disclosure, the singular forms are intended toinclude the plural forms as well, unless the context clearly indicatesotherwise.

It will be understood that when an element is referred to as being“coupled” or “connected” to another element, it can be directly coupledor connected to the other element or intervening elements may be presenttherebetween. In contrast, it should be understood that when an elementis referred to as being “directly coupled” or “directly connected” toanother element, there are no intervening elements present.

The suffixes “module” and “part” for elements used in the followingdescription are given or used in consideration of the ease of writingthe specification only, and do not have a meaning or role distinct fromeach other.

When a first part such as an element or a layer is disposed on a secondpart, the first part may be not only directly on the second part but athird part may be interposed between them. To the contrary, theexpression “the first part is directly disposed on the second part”represents that another element or layer is not interposed therebetween.

Spatially relative terms “below”, “beneath”, “lower”, “above”, “upper”,etc. may be used to easily describe a correlation between elements asshown in the drawings. Spatially relative terms should be understood asterms including different orientations of elements during use oroperation in addition to an orientation shown in the drawings.

For example, when an element shown in the drawing is turned over, anelement described as “below” or “beneath” another element may be placed“above” the other element. Therefore, the exemplary term “below” mayinclude both “below” and “above”. Elements may also be oriented in otherorientations, and thus spatially relative terms may be interpretedaccording to an orientation.

The above and other objectives, effects, and technical configurations ofthe present disclosure will be easily understood from the followingpreferred embodiments in conjunction with the accompanying drawings. Indescribing the present disclosure, if it is determined that a detaileddescription of a well-known function or configuration may unnecessarilyobscure the subject matter of the present disclosure, the detaileddescription thereof will be omitted. Since the terms can be differentlydefined according to the intention of a user or an operator or customs,these terms should be interpreted as having a meaning that is consistentwith the technical spirit of the present disclosure.

However, the present disclosure may be embodied in different formswithout being limited to embodiments set forth herein. Rather, theembodiments disclosed herein are provided to make the disclosurethorough and complete and to sufficiently convey the spirit of thepresent disclosure to those skilled in the art. The present disclosurewill be only defined by the scope of the claims. Therefore, thedefinition should be made based on the content throughout thisspecification.

In the present disclosure, a folding mat may be formed in one layer whenunfolded, and may be stacked in two layers when folded. Therefore, thefolding mat according to the present disclosure may be stacked in twolayers in a state where a cover and a cushioning material inserted intothe cover are pre-assembled, thus reducing a volume. Therefore, thefolding mat can be easily delivered. However, the size of the mat may belarge in the case of using only the above-described stacking structure,thus making it inconvenient to deliver the mat. Therefore, the foldingmat according to the present disclosure may include a plurality ofcushioning materials inserted into the cover. For example, the pluralityof cushioning materials inserted into the cover may be formed in a sizewhich is fit for a delivery box which is easily transported by a person.Thus, the folding mat according to the present disclosure can be easilydelivered by separately delivering the cover and the plurality ofcushioning materials in an unassembled state. Hereinafter, the foldingmat according to the present disclosure will be described with referenceto FIGS. 1 to 5.

FIG. 1 is a diagram illustrating an example of a folding mat accordingto some embodiments of the present disclosure.

Referring to FIG. 1, the folding mat 1000 may include a first cover part100, a second cover part 200, a first opening and closing part 300, anda second opening and closing part 400. However, the above-describedelements are not essential to form the folding mat 1000, and the foldingmat 1000 may have elements which are more or less than the above listedelements.

A plurality of first cushioning materials (not shown) may be insertedinto the first cover part 100. In this regard, the plurality of firstcushioning materials may be cushioning materials for absorbing noisewhich may be generated by a user. Hereinafter, the first cushioningmaterials will be described with reference to FIG. 2.

On the other hand, as the plurality of first cushioning materials areinserted, the first cover part 100 may form a portion of the appearanceof the folding mat 1000. However, the present disclosure is not limitedthereto.

According to some embodiments of the present disclosure, the first coverpart 100 may be formed of a fabric which does not stretch in ahorizontal direction but stretches in a vertical direction. In thisregard, the horizontal direction may be a major-axis direction of thefirst cover part 100. Further, the vertical direction may be aminor-axis direction of the first cover part 100.

For example, the first cover part 100 may be made of a fabric having acircular knit structure. Here, the circular knit structure may be astructure which is woven by needles arranged in a circular shape.Therefore, the first cover part 100 may be easily stretched by a user'sexternal force in the vertical direction, but may not be stretched inthe horizontal direction even if a user's external force is appliedthereto. However, the present disclosure is not limited thereto.

In the present disclosure, the first cover part 100 may be made of anantibacterial double-sided coating fabric having a waterproof function.In this case, the first cover part 100 may secure resistance to bacteriaand fungus. However, the present disclosure is not limited thereto.

On the other hand, the first cover part 100 may include a first side110, a second side 120, a fifth side 160 (see FIG. 4), and a seventhside 130. However, the present disclosure is not limited thereto.

The first opening and closing part 300 may be formed on at least two ofthe first side 110, the second side 120, and the seventh side 130.Further, the first opening and closing part 300 may be opened and closedsuch that the plurality of first cushioning materials may be insertedinto the first cover part 100. For example, the first opening andclosing part 300 may be provided with a zipper or the like to be openedand closed by a user. However, the present disclosure is not limitedthereto.

On the other hand, the plurality of second cushioning materials (notshown) may be inserted into the second cover part 200, and the secondcover part may be foldably connected with the first cover part 100.

For example, an area of an upper surface of the second cover part 200may be sewn on an area of an upper surface of the first cover part 100to be connected thereto. Therefore, the second cover part 200 or thefirst cover part 100 may be folded by a user. For instance, when thesecond cover part 200 is folded by a user, the second cover part 200 maybe stacked on the upper surface of the first cover part 100. On thecontrary, when the first cover part 100 is folded by a user, the firstcover part 100 may be stacked on the upper surface of the second coverpart 200. However, the present disclosure is not limited thereto.Hereinafter, an example where the folding mat 1000 according to thepresent disclosure is folded will be described with reference to FIG. 4.

According to some embodiments of the present disclosure, the secondcover part 200 may be formed of a fabric which is not stretched in thehorizontal direction and is stretched in the vertical direction. Here,the horizontal direction may be a major-axis direction of the secondcover part 200. Further, the vertical direction may be a minor-axisdirection of the second cover part 200.

For example, the second cover part 200 may be made of a fabric having acircular knit structure. Here, the circular knit structure may be astructure which is woven by needles arranged in a circular shape.Therefore, the second cover part 200 may be easily stretched by a user'sexternal force in the vertical direction, but may not be stretched inthe horizontal direction even if a user's external force is appliedthereto. However, the present disclosure is not limited thereto.

In the present disclosure, the second cover part 200 may be made of anantibacterial double-sided coating fabric having a waterproof function.In this case, the second cover part 200 may secure resistance tobacteria and fungus. However, the present disclosure is not limitedthereto.

On the other hand, the second cover part 200 may include a third side210, a fourth side 220, a sixth side 260 (see FIG. 4), and an eighthside 230. However, the present disclosure is not limited thereto.

The second opening and closing part 400 may be formed on at least two ofthe third side 210, the fourth side 220, and the eighth side 230.Further, the second opening and closing part 400 may be opened andclosed such that the plurality of second cushioning materials may beinserted into the second cover part 200. For example, the second openingand closing part 400 may be provided with a zipper or the like to beopened and closed by a user. However, the present disclosure is notlimited thereto.

On the other hand, the first opening and closing part 300 may be formedfrom a first point 140 of the first side 110 of the first cover part 100to a second point 150 of the second side 120 of the first cover part100.

To be more specific, the first opening and closing part 300 may beformed from the first point 140 of the first side 110 through theseventh side 130 to the second point 150 of the second side 120. In thisregard, the first point 140 may be a point on the first side 110 wherethe first side 110 contacts the sixth side. Further, the second point150 may be a point on the second side 120, which is spaced apart from apoint where the second side 120 contacts the sixth side by apredetermined distance. However, the present disclosure is not limitedthereto.

On the other hand, the first opening and closing part 300 may open atleast two sides of the first cover part 100 so that the plurality offirst cushioning materials are inserted into the first cover part 100.In this regard, at least two sides of the first cover part 100 equippedwith the first opening and closing part 300 may not include the fifthside of the first cover part 100, the entire surface of which contacts aside of the second cover part 200 in a state where the upper surface ofthe first cover part 100 and the upper surface of the second cover part200 are present on the same plane (a state where the folding mat is notstacked or a state where the folding mat is not folded). That is, atleast two sides may be at least two sides among the first side 110, thesecond side 120, and the seventh side 130. However, the presentdisclosure is not limited thereto.

As the first opening and closing part 300 is formed from the first point140 to the second point 150, the entire areas of the first side 110 andthe seventh side 130 of the first cover part 100 may be opened, and onlysome areas of the second side 120 may be opened. Therefore, a user mayinsert a first cushioning material among the plurality of firstcushioning materials to contact an unopened inner side of the secondside 120. In this case, the first cushioning material among theplurality of first cushioning materials may be inserted all the way toan inner end of the first cover part 100 to be positioned at a desiredlocation. Further, the user may insert the remaining first cushioningmaterials subsequent to the first cushioning material. Therefore, evenif the plurality of cushioning materials inserted into the first coverpart 100 are provided, the user can conveniently perform an operation ofinserting the plurality of first cushioning materials into the firstcover part 100. Hereinafter, the method of inserting the plurality offirst cushioning materials into the first cover part 100 according tothe present disclosure will be described with reference to FIGS. 2 and3.

According to some embodiments of the present disclosure, the firstopening and closing part 300 may be formed from the first point 140 ofthe first side 110 to a first corner of the seventh side 130. In thisregard, the first corner may be a point where the seventh side 130contacts the second side 120. Further, the first opening and closingpart 300 may open the first side 110 and the seventh side 130 so thatthe plurality of first cushioning materials are inserted into the firstcover part 100. However, the present disclosure is not limited thereto.

On the other hand, the second opening and closing part 400 may be formedfrom a third point 240 of the third side 210 of the second cover part200 to a fourth point 250 of the fourth side 220 of the second coverpart 200.

To be more specific, the second opening and closing part 400 may beformed from the third point 240 of the third side 210 through the eighthside 230 to the fourth point 250 of the fourth side 220. In this regard,the third point 240 may be a point on the third side 210 where the thirdside 210 contacts the fifth side. Further, the fourth point 250 may be apoint on the fourth side 220, which is spaced apart from a point wherethe fourth side 220 contacts the fifth side by a predetermined distance.However, the present disclosure is not limited thereto.

On the other hand, the second opening and closing part 400 may open atleast two sides of the second cover part 200 so that the plurality ofsecond cushioning materials are inserted into the second cover part 200.In this regard, at least two sides of the second cover part 200 equippedwith the second opening and closing part 400 may not include the sixthside of the second cover part 200, the entire surface of which contactsthe fifth side of the first cover part 100 in a state where the uppersurface of the first cover part 100 and the upper surface of the secondcover part 200 are present on the same plane (a state where the foldingmat is not stacked or a state where the folding mat is not folded). Thatis, at least two sides may be at least two sides among the third side210, the fourth side 220, and the eighth side 230. However, the presentdisclosure is not limited thereto.

As the second opening and closing part 400 is formed from the thirdpoint 240 to the fourth point 250, the entire areas of the third side210 and the eighth side 230 of the second cover part 200 may be opened,and only some areas of the fourth side 220 may be opened. Therefore, auser may insert a first cushioning material among the plurality ofsecond cushioning materials to contact an unopened inner side of thefourth side 220. In this case, a first cushioning material among theplurality of first cushioning materials may be inserted all the way toan inner end of the second cover part 200 to be positioned at a desiredlocation. Further, the user may insert the remaining first cushioningmaterials subsequent to the first cushioning material. Therefore, evenif the plurality of cushioning materials inserted into the second coverpart 200 are provided, the user can conveniently perform an operation ofinserting the plurality of second cushioning materials into the secondcover part 200. Hereinafter, the method of inserting the plurality ofsecond cushioning materials into the second cover part 200 according tothe present disclosure will be described with reference to FIGS. 2 and3.

In the present disclosure, the second opening and closing part 400 maybe formed from the third point 240 of the third side 210 to a secondcorner of the eighth side 230. In this regard, the second corner may bea point where the eighth side 230 contacts the fourth side 220. Further,the second opening and closing part 400 may open the third side 210 andthe seventh side 130 so that the plurality of second cushioningmaterials are inserted into the second cover part 200. However, thepresent disclosure is not limited thereto.

According to some embodiments of the present disclosure, the secondpoint 150 may be a point which is disposed on the same plane as thethird point 240 and is spaced apart from the third point 240 by a firstdistance. In this regard, the first distance may be longer than half ofthe length of a vertical side formed by the plurality of firstcushioning materials, and may be shorter than the length of the verticalside formed by the plurality of first cushioning materials.

Thus, when the first cushioning material among the plurality of firstcushioning materials is inserted into the first cover part 100 by auser, the cushioning material may be positioned so that it does notescape out of the first cover part 100 and contacts the inner side ofthe second side 120. However, the present disclosure is not limitedthereto. Hereinafter, the method of inserting the plurality of firstcushioning materials into the first cover part 100 according to thepresent disclosure will be described in detail with reference to FIGS. 2and 3.

In the present disclosure, the fourth point 250 may be a point which isdisposed on the same plane as the first point 140 and is spaced apartfrom the first point 140 by a first distance. In this regard, the seconddistance may be longer than half of the length of a vertical side formedby the plurality of second cushioning materials, and may be shorter thanthe length of the vertical side formed by the plurality of secondcushioning materials.

Thus, when the first cushioning material among the plurality of secondcushioning materials is inserted into the second cover part 200 by auser, the cushioning material may be positioned so that it does notescape out of the second cover part 200 and contacts the inner side ofthe fourth side 220. However, the present disclosure is not limitedthereto. Hereinafter, the method of inserting the plurality of secondcushioning materials into the second cover part 200 according to thepresent disclosure will be described in detail with reference to FIGS. 2and 3.

According to the above-described configuration, each of the first coverpart 100 and the second cover part 200 may be provided with the openingand closing part which may open at least two sides. In this case, evenif the plurality of cushioning materials inserted into each of the firstcover part 100 and the second cover part 200 are provided, a user mayeasily insert the plurality of cushioning materials into each coverpart.

FIG. 2 is a diagram illustrating an example of the plurality ofcushioning materials inserted into the cover part according to someembodiments of the present disclosure.

Referring to FIG. 2, the folding mat 1000 may include a plurality offirst cushioning materials 500. For example, the plurality of firstcushioning materials 500 may be two, three, or four. Furthermore, thefolding mat 1000 may include a plurality of second cushioning materials(not shown). Further, the plurality of second cushioning materials maybe two, three, or four. However, the present disclosure is not limitedthereto.

According to some embodiments of the present disclosure, the length ofthe horizontal side of the first cover part 100 may be longer than thelength of the horizontal side formed by the plurality of firstcushioning materials 500 by a preset first length to allow the pluralityof first cushioning materials 500 to be easily inserted into the firstcover part 100. In this regard, the horizontal side of the first coverpart 100 may be a side provided with the second side 120. Further, thehorizontal side formed by the plurality of first cushioning materials500 may be a side corresponding to the second side 120. However, thepresent disclosure is not limited thereto.

According to some embodiments of the present disclosure, the presetfirst length may be a length ranging from 0.5 cm or more to 1.5 cm orless. Therefore, since the length of the horizontal side of the firstcover part 100 is longer than the length of the horizontal side formedby the plurality of first cushioning materials 500, a user can easilyinsert the plurality of first cushioning materials 500 into the firstcover part 100. However, the present disclosure is not limited thereto.

On the other hand, the length of the vertical side of the first coverpart 100 may be shorter than the length of the vertical side formed bythe plurality of first cushioning materials 500 by a preset secondlength so that the plurality of first cushioning materials 500 come intoclose contact with the first cover part 100 without having a spacetherein. In this regard, the vertical side of the first cover part 100may be a side provided with the first side 110. Further, the verticalside formed by the plurality of first cushioning materials 500 may be aside corresponding to the first side 110. However, the presentdisclosure is not limited thereto.

According to some embodiments of the present disclosure, as the firstopening and closing part 300 is formed from the first point 140 to thesecond point 150, the entire areas of the first side 110 and the seventhside 130 of the first cover part 100 may be opened. Further, only someareas of the second side 120 may be opened. In this case, the firstcushioning material which is first inserted by a user among theplurality of first cushioning materials 500 may be inserted to contactthe unopened inner side of the second side 120 and thereby be positionedat a desired location.

According to some embodiments of the present disclosure, the secondpoint 150 of the second side 120 may be a point which is spaced apartfrom the third point 240 by a first distance. In this regard, the firstdistance may be longer than half of the length of a vertical side formedby the plurality of first cushioning materials 500, and may be shorterthan the length of the vertical side formed by the plurality of firstcushioning materials 500.

Thus, when at least a portion of the first cushioning material among theplurality of first cushioning materials 500 is inserted into the firstcover part 100 by a user, the cushioning material may be positioned sothat it does not escape out of the first cover part 100 and contacts theinner side of the second side 120. However, the present disclosure isnot limited thereto.

According to some embodiments of the present disclosure, the length ofthe vertical side of the first cover part 100 may be shorter than thelength of the vertical side formed by the plurality of first cushioningmaterials 500 by a preset second length. In this regard, the presetsecond length may be determined according to the following Equation.

L ₂ =L ₁ −α*L ₁  [Equation 1]

where L₁ may represent the length of the vertical side formed by theplurality of first cushioning materials 500. Further, α may represent apreset ratio value. For example, the preset ratio value may be a valueranging from 0.005 or more to 0.015 or less. Further, L₂ may representthe length of the vertical side of the first cover part 100. In thiscase, the plurality of first cushioning materials 500 may come intoclose contact with the first cover part 100 without a space therebetweento be inserted into the first cover part 100. However, the presentdisclosure is not limited thereto.

In the present disclosure, as the length of the vertical side of thefirst cover part 100 is shorter than the length of the vertical sideformed by the plurality of first cushioning materials 500 by a presetsecond length, the plurality of first cushioning materials 500 may becompressed in a vertical direction. In this case, the length of thehorizontal side of the plurality of first cushioning materials 500 maybe increased.

To be more specific, when the plurality of first cushioning materials500 are inserted into the first cover part 100 and thereby the firstopening and closing part 300 is closed, the plurality of firstcushioning materials 500 may be compressed in the vertical direction. Inthis case, the length of the horizontal side of the plurality of firstcushioning materials 500 may be increased. Therefore, the plurality offirst cushioning materials 500 may be inserted into the first cover part100 to come into close contact therewith without a space in thehorizontal direction. However, the present disclosure is not limitedthereto.

According to some embodiments of the present disclosure, the length ofthe horizontal side of the second cover part 200 may be longer than thelength of the horizontal side formed by the plurality of secondcushioning materials by a preset first length to allow the plurality ofsecond cushioning materials to be easily inserted into the second coverpart 200. In this regard, the horizontal side of the second cover part200 may be a side provided with an eighth side 230. Further, thehorizontal side formed by the plurality of second cushioning materialsmay be a side corresponding to the eighth side 230. However, the presentdisclosure is not limited thereto.

According to some embodiments of the present disclosure, the presetfirst length may be a length ranging from 0.5 cm or more to 1.5 cm orless. Therefore, since the length of the horizontal side of the secondcover part 200 is longer than the length of the horizontal side formedby the plurality of second cushioning materials, a user can easilyinsert the plurality of second cushioning materials into the secondcover part 200. However, the present disclosure is not limited thereto.

On the other hand, the length of the vertical side of the second coverpart 200 may be shorter than the length of the vertical side formed bythe plurality of second cushioning materials by a preset second lengthso that the plurality of second cushioning materials come into closecontact with the second cover part 200 without having a space therein.In this regard, the vertical side of the second cover part 200 may be aside provided with the fourth side 220. Further, the vertical sideformed by the plurality of second cushioning materials may be a sidecorresponding to the fourth side 220. However, the present disclosure isnot limited thereto.

According to some embodiments of the present disclosure, as the secondopening and closing part 400 is formed from the third point 240 to thefourth point 250, the entire areas of the third side 210 and the eighthside 230 of the second cover part 200 may be opened. Further, only someareas of the fourth side 220 may be opened. In this case, the firstcushioning material which is first inserted by a user among theplurality of second cushioning materials may be inserted to contact theunopened inner side of the fourth side 220 and thereby be positioned ata desired location.

According to some embodiments of the present disclosure, the fourthpoint 250 of the fourth side 220 may be a point which is spaced apartfrom the first point 140 by a second distance. In this regard, thesecond distance may be longer than half of the length of a vertical sideformed by the plurality of second cushioning materials, and may beshorter than the length of the vertical side formed by the plurality ofsecond cushioning materials.

Thus, when at least a portion of the first cushioning material among theplurality of second cushioning materials is inserted into the secondcover part 200 by a user, the cushioning material may be positioned sothat it does not escape out of the second cover part 200 and contactsthe inner side of the fourth side 220. However, the present disclosureis not limited thereto.

According to some embodiments of the present disclosure, the length ofthe vertical side of the second cover part 200 may be shorter than thelength of the vertical side formed by the plurality of second cushioningmaterials by a preset second length. In this regard, the preset secondlength may be determined according to the following Equation.

L ₂ =L ₁ −α*L ₁  [Equation 1]

where L₁ may represent the length of the vertical side formed by theplurality of second cushioning materials. Further, α may represent apreset ratio value. For example, the preset ratio value may be a valueranging from 0.005 or more to 0.015 or less. Further, L₂ may representthe length of the vertical side of the second cover part 200. In thiscase, the plurality of second cushioning materials may come into closecontact with the second cover part 200 without a space therebetween tobe inserted into the second cover part 200. However, the presentdisclosure is not limited thereto.

In the present disclosure, as the length of the vertical side of thesecond cover part 200 is shorter than the length of the vertical sideformed by the plurality of second cushioning materials by a presetsecond length, the plurality of second cushioning materials may becompressed in a vertical direction. In this case, the length of thehorizontal side of the plurality of second cushioning materials may beincreased.

To be more specific, when the plurality of second cushioning materialsare inserted into the second cover part 200 and thereby the secondopening and closing part 400 is closed, the plurality of secondcushioning materials may be compressed in the vertical direction. Inthis case, the length of the horizontal side of the plurality of secondcushioning materials may be increased. Therefore, the plurality ofsecond cushioning materials may be inserted into the second cover part200 to come into close contact therewith without a space in thehorizontal direction. However, the present disclosure is not limitedthereto.

According to some embodiments of the present disclosure, as the secondopening and closing part 400 is formed from the third point 240 to thefourth point 250, the entire areas of the third side 210 and the eighthside 230 of the second cover part 200 may be opened. Further, only someareas of the fourth side 220 may be opened. In this case, the firstcushioning material which is first inserted by a user among theplurality of second cushioning materials may be inserted to contact theunopened inner side of the fourth side 220 to be positioned at a desiredlocation.

According to some embodiments of the present disclosure, the fourthpoint 250 of the fourth side 220 may be a point which is spaced apartfrom the first point 140 by a first distance. In this regard, the firstdistance may be longer than half of the length of a vertical side formedby the plurality of second cushioning materials, and may be shorter thanthe length of the vertical side formed by the plurality of secondcushioning materials.

Thus, when the first cushioning material among the plurality of secondcushioning materials is inserted into the second cover part 200 by auser, the cushioning material may be positioned so that it does notescape out of the second cover part 200 and contacts the inner side ofthe fourth side 220. However, the present disclosure is not limitedthereto.

According to some embodiments of the present disclosure, each of theplurality of first cushioning materials 500 and the plurality of secondcushioning materials may be formed in a size which is fit for a deliverybox which may be easily transported by a person.

For example, each of the plurality of first cushioning materials 500 andthe plurality of second cushioning materials may have the width of 730mm, the length of 1260 mm, and the height of 80 mm. However, the presentdisclosure is not limited thereto.

According to some embodiments of the present disclosure, each of thelengths of all sides of each of the plurality of first cushioningmaterials 500 may be less than the height of a floor. Further, each ofthe lengths of all sides of each of the plurality of second cushioningmaterials may be less than the floor height. Here, the floor height isthe internal height of a general elevator installed in an apartment, andmay be approximately 2.5 m.

For example, each of the plurality of first cushioning materials 500 mayhave the horizontal length of 730 mm and the vertical length of 1260 mmThat is, both the horizontal length and the vertical length of each ofthe plurality of first cushioning materials 500 may be less than thefloor height. However, the present disclosure is not limited thereto.

According to some embodiments of the present disclosure, the sum of thelengths of any combination of two or more sides of each of the pluralityof first cushioning materials 500 may be equal to or greater than thefloor height. Further, the sum of the lengths of any combination of twoor more sides of each of the plurality of second cushioning materialsmay be equal to or greater than the floor height.

For instance, each of the plurality of first cushioning materials 500may have the horizontal length of 730 mm. In this case, the length of acombination of horizontal sides of four first cushioning materials amongthe plurality of first cushioning materials 500 may be 2920 mm That is,each of the plurality of first cushioning materials 500 may have atleast one combination where the sum of the lengths of two or more sidesis equal to or greater than the floor height. However, the presentdisclosure is not limited thereto.

According to some embodiments of the present disclosure, the pluralityof first cushioning materials 500 and the plurality of second cushioningmaterials may be made of polyethylene (PE) material. However, thepresent disclosure is not limited thereto.

According to the above-described configuration, the length of thehorizontal side of the cover part may be longer than the length of thehorizontal side formed by the plurality of cushioning materials.Therefore, a user may easily insert the plurality of cushioningmaterials into the cover part. Further, the length of the vertical sideof the cover part may be shorter than the length of the vertical sideformed by the plurality of cushioning materials. Therefore, theplurality of cushioning materials may come into close contact with thecover part without a space therebetween. However, the present disclosureis not limited thereto.

FIG. 3 is a diagram illustrating another example of a plurality ofcushioning materials inserted into a cover part according to someembodiments of the present disclosure.

Referring to FIG. 3, the plurality of first cushioning materials 500 maybe inserted into the first cover part 100 such that two cushioningmaterials are arranged in a horizontal direction and two cushioningmaterials are arranged in a vertical direction. However, the presentdisclosure is not limited thereto.

In the present disclosure, when a first cushioning material among theplurality of first cushioning materials 500 is inserted into the firstcover part 100 by a user, the cushioning material may be positioned sothat it does not escape out of the first cover part 100 and contacts theunopened inner side of the second side 120. Further, a second cushioningmaterial among the plurality of first cushioning materials 500 may bepositioned such that at least a portion of the vertical side contactsthe unopened inner side of the second side 120.

To be more specific, the second point 150 of the first opening andclosing part 300 formed on the second side 120 may be a point which isspaced apart from the third point 240 by a first distance. Here, thefirst distance may be longer than half of the length of the verticalside formed by the plurality of first cushioning materials 500, and maybe shorter than the length of the vertical side formed by the pluralityof first cushioning materials 500. For example, the second point 150 maybe formed at a point which is spaced apart from the corner formed by thesecond side 120 and the seventh side 130 by a length which is equal to ¼of the vertical side of the first cover part 100.

Thus, when the first cushioning material among the plurality of firstcushioning materials 500 is inserted into the first cover part 100 by auser, the cushioning material may be positioned so that it does notescape out of the first cover part 100 and contacts the unopened innerside of the second side 120. Further, the second cushioning materialamong the plurality of first cushioning materials 500 may be positionedsuch that at least a portion of the vertical side contacts the unopenedinner side of the second side 120. Therefore, the second cushioningmaterial among the plurality of first cushioning materials 500 may alsobe positioned at desired location. However, the present disclosure isnot limited thereto.

In the present disclosure, the length of the vertical side of the firstcover part 100 may be shorter than the length of the vertical sideformed by the plurality of first cushioning materials 500 by a presetsecond length. Thus, the plurality of first cushioning materials 500 maybe compressed in the vertical direction. Therefore, the plurality offirst cushioning materials 500 may be inserted into the first cover part100 to come into close contact therewith without having a space in thevertical direction. However, the present disclosure is not limitedthereto.

On the other hand, in the present disclosure, when the first cushioningmaterial among the plurality of second cushioning materials is insertedinto the second cover part 200 by a user, the cushioning material may bepositioned so that it does not escape out of the second cover part 200and contacts the unopened inner side of the fourth side 220. Further,the second cushioning material among the plurality of second cushioningmaterials may be positioned such that at least a portion of the verticalside contacts the unopened inner side of the fourth side 220.

To be more specific, the fourth point 250 of the second opening andclosing part 400 formed on the fourth side 220 may be a point which isspaced apart from the first point 140 by a second distance. Here, thesecond distance may be longer than half of the length of the verticalside formed by the plurality of second cushioning materials, and may beshorter than the length of the vertical side formed by the plurality ofsecond cushioning materials. For example, the fourth point 250 may beformed at a point which is spaced apart from the corner formed by thefourth side 220 and the eighth side 230 by a length which is equal to ¼of the vertical side of the second cover part 200.

Thus, when the first cushioning material among the plurality of secondcushioning materials is inserted into the second cover part 200 by auser, the cushioning material may be positioned so that it does notescape out of the second cover part 200 and contacts the unopened innerside of the fourth side 220. Further, the second cushioning materialamong the plurality of second cushioning materials may be positionedsuch that at least a portion of the vertical side contacts the unopenedinner side of the fourth side 220. Therefore, the second cushioningmaterial among the plurality of second cushioning materials may also bepositioned at desired location. However, the present disclosure is notlimited thereto.

In the present disclosure, the length of the vertical side of the secondcover part 200 may be shorter than the length of the vertical sideformed by the plurality of second cushioning materials by a presetsecond length. Thus, the plurality of second cushioning materials may becompressed in the vertical direction. Therefore, the plurality of secondcushioning materials may come into close contact therewith to have nospace in the vertical direction, and may be inserted into the secondcover part 200. However, the present disclosure is not limited thereto.

According to some embodiments of the present disclosure, each of theplurality of first cushioning materials 500 and the plurality of secondcushioning materials may be formed in a size which is fit for a deliverybox which may be easily transported by a person.

For example, each of the plurality of first cushioning materials 500 andthe plurality of second cushioning materials may have the width of 1910mm, the length of 705 mm, and the height of 80 mm. However, the presentdisclosure is not limited thereto.

According to some embodiments of the present disclosure, each of thelengths of all sides of each of the plurality of first cushioningmaterials 500 may be less than a floor height. Further, each of thelengths of all sides of each of the plurality of second cushioningmaterials may be less than the floor height. Here, the floor height isthe internal height of a general elevator installed in an apartment, andmay be approximately 2.5 m.

For example, each of the plurality of first cushioning materials 500 mayhave the horizontal length of 1910 mm and the vertical length of 705 mmThat is, both the horizontal length and the vertical length of each ofthe plurality of first cushioning materials 500 may be less than thefloor height. However, the present disclosure is not limited thereto.

According to some embodiments of the present disclosure, the sum of thelengths of any combination of two or more sides of each of the pluralityof first cushioning materials 500 may be equal to or greater than thefloor height. Further, the sum of the lengths of any combination of twoor more sides of each of the plurality of second cushioning materialsmay be equal to or greater than the floor height.

For instance, each of the plurality of first cushioning materials 500may have the horizontal length of 1910 mm. In this case, the length of acombination of horizontal sides of two first cushioning materials amongthe plurality of first cushioning materials 500 may be 3820 mm That is,each of the plurality of first cushioning materials 500 may have atleast one combination where the sum of the lengths of two or more sidesis equal to or greater than the floor height. However, the presentdisclosure is not limited thereto.

According to the above-described configuration, a user may insert theplurality of cushioning materials into the cover part in a directiondifferent from that shown in FIG. 2. In other words, a user can insertthe plurality of cushioning materials into the cover part in a directionwhich is more convenient for the user to work according to the user'stendency. Therefore, it may be convenient to install the folding mat1000.

The convenience of installing the folding mat 1000 according to someembodiments of the present disclosure was proved by comparison withcomparative examples which are commercially available products as shownin Table 1 below.

TABLE 1 Comparative Comparative Effi- example 1 example 2 Embodimentciency Structure 8-layer mat 8-layer mat 2-layer mat (layer) Number of8EA 8EA 2EA opening and closing part (zipper) (EA) Number of 8EA 8EA 8EAcushioning material (EA) Insert time of 30 s 30 s 10 s   3 timescushioning material (sec) Total assembly 36 minutes 36 minutes 6 minutes5.5 times time (min) (1 group of (1 group of 30 seconds 3 persons/12 3persons/12 (1 group of minutes per minutes per 1 person) person) person)Assembly Professional Professional Ordinary experience man with man withwoman with more than more than 3 no assembly 3 years of years ofexperience experience experience

As described above with reference to FIGS. 2 and 3, this embodiment maybe provided with a plurality of cushioning materials inserted into thecover part. In contrast, according to comparative examples, only onecushioning material may be inserted into one cover part. Therefore,according to the comparative examples, a product may be inevitablymanufactured to have many layers in the structure, in order to make aproduct of the same size as this embodiment. This may show that thepresent embodiment is more efficient than the comparative example in themanufacture of products.

In comparative examples 1 and 2, one cushioning material per one openingand closing part (or cover part) may be inserted. In this case, it maytake 30 seconds to insert one cushioning material into one opening andclosing part.

On the contrary, in this embodiment, four cushioning materials per oneopening and closing part (or cover part) may be inserted. In this case,it may take 10 seconds to insert one cushioning material into oneopening and closing part. Therefore, in order to install the two-layermat according to this embodiment, it may take 80 seconds to insert thecushioning material. Since the cushioning material according to thepresent embodiment is configured in a small size for the purpose ofconvenient delivery and assembly, it may take less time to insert onecushioning material into one opening and closing part. On the contrary,since the comparative examples are configured such that one cushioningmaterial is inserted into one opening and closing part, it may take alot of time to insert one cushioning material due to an increase in thesize of the cushioning material.

On the other hand, in comparative example 1, a total assembly time maybe about 36 minutes. In this regard, the total assembly time may includetime for placing the mat at an appropriate position on a floor, inaddition to time for inserting the cushioning material into the openingand closing part. Further, in comparative example 2, a total assemblytime may be about 36 minutes. In addition, the total assembly time ofcomparative examples 1 and 2 may be time required for three professionalmen to assemble the product.

In contrast, in this embodiment, a total assembly time may be about 6minutes 30 seconds. In addition, the total assembly time of thisembodiment may be time required for one ordinary woman having noassembly experience to assemble the product. In comparative examples 1and 2, as the mat is formed in 8 layers, the assembly order may also becomplicated, and it may also take a lot of time to unfold. For instance,in the case of the 8-layer mat, it may be necessary to assemble the matpositioned in the center prior to the mat positioned at the outermostportion. In this case, in order to assemble the mat positioned in thecenter, the mat positioned at the outermost portion should be folded,and a user should perform work on the upper surface of the matpositioned at the outermost portion. Further, the unfolding of thefolded mat may be labor-intensive. On the contrary, since thisembodiment is configured in two layers, all of the above-describedinconveniences may be eliminated. However, the present disclosure is notlimited thereto.

FIG. 4 is a diagram illustrating an example when the folding mat isfolded according to some embodiments of the present disclosure.

Referring to FIG. 4, the folding mat 1000 may be folded according to auser's needs.

To be more specific, an area of the upper surface of the first coverpart 100 and an area of the upper surface of the second cover part 200may be sewn to be connected to each other. Therefore, the first coverpart 100 or the second cover part 200 may be folded by a user's externalforce.

For instance, the second cover part 200 may be stacked on the uppersurface of the first cover part 100 by the user's external force. On thecontrary, the first cover part 100 may be stacked on the upper surfaceof the second cover part 200 by the user's external force. However, thepresent disclosure is not limited thereto.

According to the above-described configuration, when a thicker mat isrequired or the folding mat 1000 needs to be positioned on only one sideof a living room, either of the first cover part 100 or the second coverpart 200 may be folded.

FIG. 5 is a diagram illustrating an example of the zipper provided onthe first opening and closing part according to some embodiments of thepresent disclosure.

Referring to FIG. 5, at least one zipper 310 may be fastened to thefirst opening and closing part 300. In this case, a user may easily openor close the first opening and closing part 300 through at least onezipper 310. However, the present disclosure is not limited thereto.

On the other hand, the first cover part 100 may include a first zippercover 111. For example, the first zipper cover 111 may be provided onthe first point 140. In this case, at least one zipper 310 may beinserted into the first zipper cover 111. Therefore, at least one zipper310 may not be exposed to the outside if unnecessary. However, thepresent disclosure is not limited thereto.

In the present disclosure, the first cover part 100 may have a secondzipper cover (not shown) on the second point 150. However, the presentdisclosure is not limited thereto.
